technology selection and commitment in new product development the role of uncertainty and Design Flexibility
Management Science, 2002Co-Authors: Viswanathan Krishnan, Shantanu BhattacharyaAbstract:Selecting the right technologies to incorporate in new products is a particularly challenging aspect of new product definition and development. While newer advanced technologies may offer improved performance, they also make the product development process more risky and challenging. In this paper, we focus on the problem of technology selection and commitment under uncertainty, a major challenge to firms in turbulent environments. We argue that the "pizza-bin" approach of rejecting prospective technologies outright may not serve firms well when the pressure to differentiate products is enormous. After motivating the challenges and decisions facing firms using a real-life application from Dell Computer Corporation, we formulate a mathematical model of a firm that must define its products in the presence of technology uncertainty. Specifically, the firm faces two options: (i) aproven technology that is known to be viable and (ii) aprospective technology that offers superior price to performance results but whose viability is not a fully certain outcome. To minimize the impact of technology uncertainty, we consider two approaches to Design Flexibility, termedparallel path andsufficient Design, which allow the firm to concurrently develop its products while the technology is being validated. Our analysis helps understand appropriateness of the different flexible Design approaches. We illustrate our model with the Dell portable computer example and note the managerial implications of our analysis.

Economic performance evaluation of process system Design Flexibility options under uncertainty: The case of hydrogen production plants with integrated membrane technology and CO2 capture
Computers and Chemical Engineering, 2017Co-Authors: Liang Chih Ma, Nikolaos K. Kazantzis, Bernardo Castro-dominguez, Yi Hua MaAbstract:A hydrogen production plant with integrated catalytic membrane reactor modules (HP-CMR) represents a new technology option with potentially enhanced environmental performance characteristics. Therefore, HP-CMR techno-economic performance in the presence of irreducible sources of uncertainty (market, regulatory) ought to be comprehensively evaluated in order to accelerate the realization of future demonstration plants. The present study introduces a systematic methodological framework allowing the economic value assessment of various Flexibility options in the Design and operation of an HP-CMR plant under the above uncertainty sources. The primary objective is to demonstrate the potentially value-enhancing prospects of Design Flexibility options that capture the inherent optionality element in managerial decision-making to actively respond to uncertainties as they are progressively resolved. A detailed Net Present Value (NPV)-based assessment framework is first developed within which the above sources of uncertainty are integrated through Monte Carlo techniques. Various constructional and operational Flexibility options are introduced pertaining to the installation decision and operating mode choice of the carbon capture and sequestration (CCS) unit, and HP-CMR economic performance is comparatively assessed. Finally, under certain scenarios of regulatory action on CO2emissions, it is demonstrated that quite appealing economic performance outcomes could emerge for HP-CMR plants once Design Flexibility is introduced.

Developing an optimized strategy achieving Design Flexibility in small-area units: Case study of Egyptian economic housing
Alexandria Engineering Journal, 2018Co-Authors: Ahmed A. Elkady, Mohamed Anwar Fikry, Zeyad El-sayadAbstract:Abstract Some countries, especially Egypt, have sought to use small housing units as a solution for housing financial problems. Unfortunately, householders faced various problems with units’ Design which obliged them to either leave their units, modify them to meet their needs, or live in their poorly Designed units. The current work aims at obtaining an optimized Design strategy through applying the “Design Flexibility” concept on economic housing units. The achieved strategy was investigated on a selected case study in Egypt, namely: Mubarak housing for youth. This strategy led to area optimized utilization. Hence, involving Design Flexibility makes the units more suitable and affordable for individuals, Fundable for the economy and friendly for the environment (reduce wasted material and energy). Therefore, Design Flexibility matches the sustainability principles (social, economic and environmental).

Safety Consequences from Design Flexibility in Rural to Urban Transitions
Advances in transportation studies, 2006Co-Authors: Nikiforos Stamatiadis, Jerry G. Pigman, Don HartmanAbstract:While all roadway Design is situation-specific and requires balancing unique local elements and needs, rural roadway Design requires even more Flexibility (and possibly variance from tradition) while still remaining within the ranges of AASHTO's "Green Book." Rural Design's unique considerations include the needs of both through and local users and speed reductions when the roadway transitions into more populous areas. The authors present case studies throughout the U.S. showing minor Design Flexibility in rural areas had few discernable effects on safety, but supported staying within "Green Book" Design values.

Safety Consequences from Design Flexibility in Rural-to-Urban Transitions
2006Co-Authors: Jerry G. Pigman, Nikiforos Stamatiadis, Don HartmanAbstract:Roadway Design could be viewed as a balancing act of the various elements and constraints that are present and is very specific to the situation in which they have to be considered. This need is even greater for roadways that pass through rural communities because of the need to reduce speed upon entering the built-up sections and to address the needs of through and local users. Therefore, such projects may require the use of Flexibility in Design and variation from the normally used values or traditional solutions while utilizing the inherent existing Flexibility within the Green Book. This paper presents a recently completed research through the identification and selection of cases studies throughout the nation which were projects where Flexibility was applied for roads that transition from a rural to a built-up area or pass through a built-up area on a predominantly rural section of roadway. The findings indicate that the relatively minor exercises of Design Flexibility, as practiced in 22 case studies, produced very few discernible effects on safety. Multiple years of crash data for each project were collected and each site-specific crash was examined (using before and after analysis and an expert panel) to assess the potential for safety consequences related to the Design Flexibility exercised. Based on these data and case study analyses, it is clear that staying within the range of Green Book Design values (or using slightly less desirable values through Design exceptions) provided an acceptable level of safety.
